This was a fantastic trip which offered a really good mixture of cycling & sightseeing (countryside, cities, historical monuments & wonders of the world).
I especially loved the cycling in Thailand, which is where most of the riding is done (the trip notes are not up to date so the mileage each day is a bit different in reality). The Thai cycling team are absolutely fantastic so you can go as fast or as slow as you like & I loved going for it. The feeling of freedom cycling along long rural roads in the sun passing, among other things, paddy fields, water buffalo & rubber tree plantations is amazing.
In Cambodia it is more about the sights - Angkor Wat, killing fields etc so there is less cycling & what there is is a bit slower & the group has to stay together due to the roads being very busy. I would recommend reading up a little in advance of the trip so you can make the most & really understand what you're going to see as the local guides cant possibly tell you everything.
In Vietnam again the cycling is quite easy but it's a really amazing place. The people of Vietnam are so welcoming with the homestay & Saigon being two of my favourite parts of the whole trip. The optional visit to the Cu Chi Tunnels is also a must.
